Answer:
Step-by-step explanation:
760·0.5^(t/9) = 19
0.5^(t/9) = 19/760
2^(-t/9) = 0.025
-t/9 = log₂(0.025)
t = -9log₂(0.025) = 47.9 minutes
Answer:
47.9 minutes

Answer:
<B = 56.25°
Step-by-step explanation:
Reference angle = B
Hypotenuse = AB = 9
Adjacent = BC = 5
Applying trigonometric ratio:
[tex] cos (B) = \frac{adj}{hyp} [/tex]
[tex] cos (B) = \frac{5}{9} [/tex]
[tex] B = cos^{-1}(\frac{5}{9}) [/tex]
B = 56.25° (nearest hundredth)

Required
Find ?
Apply law of indices
[tex]x^{-?} = x^6[/tex]
Cancel x on both sides

Molly and George earned 352 points together. Molly has half the number of points as
George. Which equation could represent this situation? Let g represent the number of
points George earned.
Answer:
Assume G = George
I can use the problem to find that:
G + 1/2G = 352

Bertie Beetke Walks so that he is always exactly 1.3 cm. Adam and walks so that he is always exactly 3.5 cm from crumb B the only two points at which they can meet, mark the points with crosses.
Answer:
I can not give an exact solution, because I can not draw in the given image and I don't know the scale of the image, but I can give a general way of solving this.
We know that a circle is a shape such that al the points are equidistant to the center.
So, if Bertie is always exactly 1.3cm from crumb A, then all the possible positions of Bertie are shown by a circle of radius = 1.3cm around crumb A.
And if Adam is always exactly 3.5cm away from crumb B, then the possible positions of Adam are shown by a circle of radius = 3.5cm around crumb B.
So to solve this problem, you need to draw these two circles, and the points where the circles intersect each other will be the points where Bertie and Adam could meet.

then which of the following is the measure of
a 76
b 90
C 38
d 48
HELP ME PLEASE !!! thank you
Answer:
<STR = 38degrees
Step-by-step explanation:
Find the diagram attached
Complete Question:
In Rhombus QRST, diagonals RT and QS are drawn. If m<TSR = 104°, then which of the following is the measure of <SRT?
Sicne triangle STR is isosceles, hence the base angles are equal. Let the base angles be y
y+y+104 = 180
2y = 180-104
2y = 76
y = 38degrees
Since <STR = y, hence the measure of <STR = 38degrees

A school paid 31.50 for each calculator
If the school bought x calculators, how much did
they pay? Write an expression.
The salaries of 4 players on a professional basketball
team average $200,000 per year. If a fifth player is hired
for $400,000 per year, what will be the average salary
for the 5 players?
If salary average of 4 players is making $200,000/yr, what's the total payroll? It should be $200K x 4 or $800,000.
Now if you add in that 5th player at $400,000 what is the total payroll of all 5 players? It should be $800,000 + $400,000 = 1,200,000. From there you can find the average of the 5 players by dividing!

find the value of x
Answer:
x = 4
Step-by-step explanation:
10x + 140 = 180
10x = 40
x = 4
Answer:
x = 4
Step-by-step explanation:
I did 140 + 10x = 180
Then I solved by subtracting 180 - 140 to get:
10x = 40
Next you divide 10 on both sides to get 4 as x

Fill in the blanks to make a true statement.
(2+___i) + (___+3i) = 6 + 8i
Answer:
(2+ 5i) + (4 + 3i) = 6 + 8i
Step-by-step explanation:
2 + xi + y + 3i = 6 + 8i
(2 + y) + xi + 3i = 6 +8i
(2 + y) + (x + 3)i = 6 + 8i
Compare real numbers
2 + y = 6
y = 6 - 2
y = 4
Compare imaginary numbers
x + 3 = 8
x = 8 - 3
x = 5
